However, as DHCP can do much more than simply provide an IP address, having DHCP would have been advantageous at times.

- When validating dates, sometimes it's easiest to just let people type whatever they want and have your code try to make sense of it. Of ourse if you can constrain people to specific formats, that's even easier, but that's not always an option - your input may be coming from multiple sources where different rules or expectations are in effect.
